The invention relates to a double-speed permanent magnet, excitement-electricity excited complex synchronous motor, which pertains to the motor field and solves the problem that a permanent magnet motor can not change poles and regulate speed and that an electricity excited motor has small power factor and low efficiency. The double-speed motor of the invention is provided with two rotor poles: P1and P2; all N poles and S poles are evenly distributed and arrayed in an interleaving way along the circumferential direction on the surface of a rotor; the rotor poles of two poles are superimposed;areas with the same polarity are provided with permanent magnets when the number of poles of all the rotors of the motor is P1 or P2, and the polarity is the same as the polarity when the number of poles of the rotors of the motor in the same area is P1 or P2; areas with the opposite polarity are provided with electromagnetic windings when the number of poles of all the rotors of the motor is P1or P2; when the number of poles of the rotors of the motor is P1, the polarity of the electromagnetic windings is the same as the polarity of P1 pole rotor in the same area; when the number of poles of the rotors of the motor is P2, the polarity of the electromagnetic windings is the same as the polarity of P2 pole rotor in the same area; adjacent rotor poles with the same polarity are synthesizedinto a rotor pole to be used.
